I'll say this one more time but that's it, volume is not mass. The displacement of a floating object is exactly the weight of the water displaced by the immersed portion of the object, regardless of shape or volume. When we refer to the volume of a hull it's not just the immersed portion it's the entire hull.
The Seapiper website states a dry weight of 13500 pounds and it's irrelevant to all but the half a dozen people that can afford a truck to tow the thing after spending all day pumping the fuel, oil and water out along with unloading every other item on the boat.
The relationship between the volume of water and its weight is fixed here on Earth. So the "exactly the weight of the water displaced...regardless of the volume" is simply wrong. Tell me the volume and I'll tell you the weight. ...

Tell me the volume and I'll tell you the weight. Also, when you add draft it is generally defined to be below the waterline and therefore immersed.
Seapiper lists the dry weight in two places, 13,500 on the website spec and 12,500 on their brochure. I'd suspect both are optimistic. Nevertheless, I already own the truck and about 1/2 million of these trucks are sold each year, so I think more than a half dozen other people might as well. (In any case a used one could be bought for <5% of the boat purchase price, or hired when needed.) I would plan my refueling and water to be nearly empty when I trailered and would not unload anything else. If the weight of the oil made a difference then yeah, you probably do need a bigger truck. Getting it ready for the trailer would be a one hour exercise.
I guess those saying the Seapiper can't be trailered have never seen a large 5th wheel RV. They are 45' long and 20,000 lbs. 75 year olds drive them all over the country, with pickup trucks bought off the lot.
But, not a lot of difference between fresh and salt (3%).Also need to know the type of water.
Fuel sipping, huge range, shallow draft, no *bling* and a box keel with protected prop so you can let it dry when and where you want. Affordable as well.
Some people love to spend time aboard in sumptuous luxury...other people might see their boat as a means to get somewhere, then get off the boat to do stuff in otherwise inaccessible coastal areas...a base camp to further adventure.
Oh, and trailerable, which is a huge plus for expanding your cruising range!
Good point.
Each persons perfect boat, if such a thing even exists, is a boat with the least amount of compromises.
